Lantern-shaped platinum(III) complexes with axially bound 9-ethylguanine or 1-methylcytosine (L) of general formula [Pt2{HN=C(Bu t)O}4L2](NO3)2

Abstract

The synthesis, NMR characterization, and X-ray crystallography of lantern-shaped platinum(III) complexes with four pivaloamidate bridging ligands and two 9-ethylguanines (9-EtG) or 1-methylcytosines (1-MeC) in axial positions are reported: cis-N2O2-[Pt2HN=C(Bu t)O}4(9-EtG)2](NO3)2 and cis-N2O2-[Pt2HN=C(But)O} 4(1-MeC)2](NO3)2. The last complex is, to the best of our knowledge, the first dinuclear compound of platinum(III) with axially bound 1-MeC. Copyright © 2010 Concetta Pacifico et al.
